I don't know if this is correct but according to tv.com, guests mentioned that there was two scenes ever in this sketch. First one was Ed Norton in the sewer, cleaning his teeth and singing. The second one took place at a restaurant. It was said that after this aired, Gleason destroyed all copies because it was such a bomb.

Thats not new news. It's correct. This has been posted for over a decade.
So glad there is another new post with this.

Sorry. I thought that the two scenes info. Was news.

Art Carney made 2 recordings in his Ed Norton character, I have a 78 with "Norton" singing: "Va Va Va Voom" & "Song Of The Sewer". I wonder if it was either of these songs that Norton sang in that special? I have since transferred my 78 over to a CD and then onto my computer's playlist. So it still pops up occasionally (I set the playback to "Random" so it skips around) when listening to my music. Norton is alive and singing in my world.:crazy:
